1b447e8d19 Scheduler: Logging cleanup in predicates.go. 
This is some light cleanup of logs in predicates.go. In particular, some
log lines have details clarified that will make debugging easier.

I have not touched any VLOG messages, since those usually have plenty of
detail.

954996e231 Move from glog to klog 
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
  * github.com/kubernetes/repo-infra
  * k8s.io/gengo/
  * k8s.io/kube-openapi/
  * github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

d85daf0f4c Resolves #59015, extends existing regex to cover t3, r5(d) & z1d instance types 
From current AWS documentation:

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/volume_limits.html

T3, C5, C5d, M5, M5d, R5, R5d, and z1d instances support a maximum of
28 attachments, and every instance has at least one network interface
attachment. If you have no additional network interface attachments on
these instances, you could attach 27 EBS volumes.
